The share of pre-tax income flowing to the top of the UK income distribution increased continually and substantially in the three decades leading up to the financial crisis, but has changed little since 2013. Using microdata sampled from UK tax records, we describe the nature of top incomes in...

Countries that implement wealth taxes make many practical compromises regarding relative treatment and approach to valuation of different categories of assets in order to ease assessment and liquidity difficulties with this form of taxation. Relying on Norwegian variation in tax and base rules,...

This paper reports new evidence that giving financial rewards for adopting a child from foster care or becoming a kin guardian improves the later school performance of these children. It uses linked administrative data to examine a policy change in Minnesota. This change increased the payments...

Families provide substantial care to older adults with functional limitations. Policies that incentivize work have the potential to reduce this valuable care. This study uses the Health and Retirement Study (HRS) and a simulated instrument approach to examine the consequences of increases in the...

When is a wealth tax preferable to a capital income tax? When is the opposite true? More generally, can capital taxation be structured to improve productivity, incentivize innovation, and ultimately increase welfare? We study these questions theoretically in an infinite-horizon model with...

Over half of the U.S. population receives health insurance through an employer, with employer premium contributions creating a flat "head tax" per worker, independent of their earnings. This paper develops and calibrates a stylized model of the labor market to explore how this uniquely American...

We estimate the extensive and intensive margin labor supply response to the monthly Child Tax Credit disbursed in 2021 as a part of the American Rescue Plan Act. Using Current Population Survey microdata, we compare labor supply outcomes among households who qualify for varying relative...

This article explores subjects in optimal income taxation characterized by recent research interest, practical importance in light of concerns about inequality, potential for misunderstanding, and prospects for advancement. Throughout, the analysis highlights paths for further investigation....
